Description
The application is application number is 200780046002.2, the applying date be December 12 in 2007 day, be called the divisional application of the Chinese invention patent application of " for transmitting and receiving the method and apparatus of grouping via high-speed downlink packet access ".
Technical field
The present invention relates to wireless communication system.
Background technology
HSDPA is a kind of feature introduced in the version 5 of third generation partner program (3GPP) specification, to improve data rate in for the down link of packet data user.Down link data is transmitted into wireless transmitter/receiver unit (WTRU) via high-speed downlink shared channel (HS-DSCH) by Node B.Feedback is sent to Node B via high-speed dedicated control channel (HS-DPCCH) by WTRU.
Adaptive Modulation and Coding (AMC), mixed automatic repeat request (H-ARQ) and fast Node B scheduling is a part for the new feature in HSDPA.AMC carrys out the transmitted data rates on adaptive HS-DSCH according to the channel condition that WTRU discovers.Node B determination iptimum speed and use following information to dispatch individual transmission:
(1) from the CQI (CQI) of WTRU report, it indicates the quality of the channel discovered by WTRU;
(2) transmitting power of the dedicated channel be associated controls (TPC) order; And
(3) in response to affirmative acknowledgement (ACK)/negative response (NACK) feedback that previous HS-DSCH transmits.
Lower data rate is generally used for the transmission (such as, at cell edge place) to the WTRU perceiving unfavorable channel condition, thus produces less transmission chunk in the Transmission Time Interval (TTI) of each 2ms.Higher data rate is used for the transmission to the WTRU perceiving favorable channel condition, thus in the TTI of each 2ms, produce larger transmission chunk.
WTRU reports CQI by HS-DPCCH, the instruction of the channel quality providing the WTRU in down link to perceive to Node B whereby.CQI indicates WTRU may receive the highest MAC-hs transmission chunk sizes in the downlink in the TTI of 2ms, and its transmission BEP is less than 0.1 (namely 10%).For classification 10WTRU CQI and transmission chunk sizes between mapping as shown in table 1.Different CQI question blanks is provided to each WTRU classification.Higher CQI value corresponds to larger transmission chunk sizes.
Table 1
An important application for HSDPA is the transmission of ip voice (VoIP) business.VoIP is a kind of emerging technology by packet switching network transferring voice.Because end-to-end delay has the strictest requirement, VoIP is different from non real-time data-oriented application significantly in service quality (QoS).
Fig. 1 shows the protocol architecture of the VoIP transmission in Universal Mobile Telecommunications System (UMTS).Voice signal is encoded in some frames of 20ms duration by speech codec.Then, encoding speech signal is transmitted by RTP (RTP), User Datagram Protoco (UDP) (UDP) and Internet protocol (IP).The online transmission of packet switching, the agreement generally all accepted is existed for speech business.
Fig. 2 shows traditional VoIP and divides into groups.According to IP version (i.e. IPv4 or IPv6), the size that the VoIP launched by radio net is divided into groups can be 72 or 92 bytes.Refer again to Fig. 1, VoIP grouping is delivered to PDCP (PDCP) layer, and this PDCP (PDCP) layer compresses RTP, UDP and IP header by air interface transmission.PDCP layer uses robust header compression (ROHC).A large amount of state can be defined for ROHC during single voip call.In a state, the complete frame without any compression can be delivered to lower level to transmit.In another kind of state, ~ the compression completely of the RTP/UPD/IP header of 1 byte may be low to moderate.This produces scope from 33 bytes to the variable packets size of 92 bytes.
Then, the PDCP layer grouping after compression is delivered to wireless spread-spectrum technology (RLC) layer.Rlc layer generally works with the non-answer-mode (UM) divided into groups for VoIP.One (1) additional byte header is attached to the grouping of PDCP layer by rlc layer.The magnitude range being delivered to the rlc protocol data cell (PDU) of medium access control (MAC) layer is from 34 bytes (the full header-compressed with IPv4) to 93 bytes (without header-compressed).MAC layer comprises one or more RLC PDU (each RLC PDU corresponds to VoIP grouping) at the single transmission chunk for transmitting.
WTRU reports by sending CQI to Node B the downlink channel quality perceived.CQI indicates the maximum transmitted chunk sizes that WTRU can receive by the probabilities of packet error of 10%.Correspond to less transmission chunk sizes, low CQI value is reported to Node B in severe channel conditions.In some cases, next grouping being launched into WTRU may be greater than the maximum transmitted chunk sizes specified via CQI.VoIP service is thought of as an example, wherein, the magnitude range of RLC PDU is from 272 bits (34 byte) to 736 bits (92 byte), and according to table 1, CQI value 1,2 and 3 suggested for transmission chunk too little 272 bit RLC PDU.Similarly, CQI value 1 to 7 suggested for transmission chunk sizes too little maximum RLCPDU (i.e. 736 bits).
When CQI instruction is less than the chunk sizes of next grouping in queue, Node B may be reacted in two different ways.Node B can wait until that channel condition improves and WTRU instruction WTRU can with till rational error probability reception MAC-hs PDU always.Alternatively, Node B also can launch be greater than CQI instruction size transmission chunk and depend on grouping Successful delivery H-ARQ process.
In the first approach, Node B does not dispatch any transmission to WTRU, until Node-B receiver is to the CQI even as big as launching next grouping in queue.Because larger CQ report is only reported when channel condition improves, so this can adopt the time quantum of expansion.This approach may be suitable for can the non real-time application of tolerate variable delays, but not by the delay-sensitive application of such as VoIP and so on is accepted.
In the second approach, Node B no matter bad CQI and to VoIP scheduling packet transmissions.Because transmission chunk is greater than the transmission chunk that can receive with 10% probability of error, so described transmission probably failure.After Successful transmissions occurs in the re-transmission via certain quantity of H-ARQ mechanism the most at last.But H-ARQ retransmits the delay introducing and do not conform to application needs in real time.Especially for the user perceiving bad channel condition, traditional HSDPA system does not have transmitting real-time service effectively.
Summary of the invention
Disclose a kind of for the method and apparatus via HSDPA transmitting and receiving grouping.At least one HSDPA medium access controls (MAC-hs) service data unit (SDU) and is divided into multiple segmentation.Multiple MAC-hs PDU generates from described segmentation, and wherein, each MAC-hs PDU comprises at least one segmentation.Each MAC-hs PDU may comprise a segmentation from single MAC-hs SDU.Except last segmentation of MAC-hs SDU, the size that the size of described segmentation and the size of MAC-hsPDU deduct MAC-hs PDU header matches.The number of fragments be split to form based on MAC-hs SDU determines the size of segmentation.The segmentation comprised in MAC-hs PDU is at random selected.Alternatively, each MAC-hs PDU can comprise the combination of the piecewise combination from multiple MAC-hs SDU or at least one segmentation from a MAC-hs SDU and at least one complete MAC-hsSDU.

Embodiment described herein can be implemented in any wireless communication system, and described wireless communication system includes but not limited to 3GPP UMTS wireless communication system.
In order to improve the transmission of delay-sensitive data (such as, VoIP business), in the down link for HSDPA system, can in MAC-hs layer segmentation grouping.Larger grouping is divided into less grouping, so that the sequential delivery compared with subsection allowing reliability higher.This allows Node B launch segmentation by multiple TTI, thus reduces the transmission chunk sizes in each TTI.Less transmission chunk can be launched with lower modulation and/or compared with high code-rate, retransmit with minimized H-ARQ to guarantee to transmit more reliably.
Fig. 3 shows the functional structure of the MAC-hs layer 300 in Node B.MAC-hs layer 300 comprises scheduling and priority treatment entity 302, segmentation entity 306, H-ARQ entity 308 and transformat and combination of resources (TFRC) select entity 310.MAC-hs SDU is received from higher level (such as, MAC-d layer), is then stored in one of multiple Priority Queues 305 according to priority queue distribution function 304.Scheduling and priority treatment entity 302 are that each new MAC-hs PDU manages and determines queue ID and TSN.
Segmentation entity 306 is comprised in the MAC-hs layer 300 of Node B, and therefore at least one MAC-hs SDU is divided into multiple segmentation.At least one MAC-hs SDU can be divided into multiple segmentation by divided entity 306.Then, the MAC-hs PDU launched via H-ARQ entity 308 comprises at least one segmentation.Respectively for each MAC-hs PDU, perform H-ARQ process by air interface.TFRC selects entity 310 to be that each MAC-hs PDU selects transformat and resource.MAC-hs PDU is transmitted wirelessly via physical layer 320.
Fig. 4 shows the functional structure of the MAC-hs layer 400 in WTRU.MAC-hs layer 400 comprises H-ARQ entity 402, queue and rearrangement distribution 404, reordering entity 406, restructuring entity 408 Sum decomposition entity 410.H-ARQ entity 402 receives MAC-hs PDU via physical layer 420.According to transmission sequence number (TSN), the MAC-hs PDU received distributes 404 via queue and rearrangement and is sent to reordering entity 406 to resequence.MAC-hs PDU after rearrangement is recombinated by entity 408 of recombinating.MAC-hs PDU after restructuring is sent to and decomposes entity 410, to extract the MAC-hs SDU that will be sent out higher level (such as, MAC-d layer).
The segmentation of the PDU between Node B and WTRU and the coordination of restructuring can by use by the new MAC-hs header that is described in more detail below or via High-Speed Shared Control Channel (HS-SCCH) by signals.
Fig. 5 shows the MAC-hs SDU splitting scheme according to the first execution mode.MAC-hs SDU502 (such as MAC-d PDU) can be divided into multiple segmentation.Each MAC-hs PDU504a-504n comprises the single split 508a-508n from being no more than a MAC-hs SDU 502.Except last segmentation, the size of each segmentation just in time deducts MAC-hs header size with the size of MAC-hs PDU and matches.The MAC-hs PDU 504n comprising last segmentation can comprise filling bit 510.
Fig. 5 also show the MAC-hs header format according to the first execution mode.MAC-hs header 506a-506n indicates MAC-hs splitting scheme.MAC-hs header 506a-506n comprises version sign (VF), queue ID, TSN, size identifier (SID) and fragment (fragment) sequence number (FSN).It should be pointed out that the correct order of the information element in MAC-hs header 506a-506n is inessential, and can change.
1 traditional bit VF field can from a bit expanded to two (2) bits.First bit can be set to ' the previous reserved value of 1'() to indicate the new MAC-hsPDU form supporting MAC-hs SDU segmentation.Only have when a MAC-hs SDU is divided into two or more segmentation, just should use new MAC-hs PDU form.Otherwise, MAC-hs SDU should be transmitted with traditional MAC-hs PDU form.Second bit of VF field can be set to ' 0', and be worth ', and 1' specializes in following object and is reserved.
Queue ID identifies the queue and rearrangement in WTRU, to support the individual buffer process belonging to the data of different queue and rearrangement.TSN is the identifier of the transmission sequence number on HS-DSCH.TSN is for resetting object to support to send to higher level according to the order of sequence.SID is the identifier for MAC-hs SDU size.Optionally, SID can be omitted in office why not comprising in the MAC-hs PDU of the first segmentation.FSN is optional and provides the identifier for fragment sequence number.
Optionally, additional 1 bit flag (not shown in Fig. 5) can be added to MAC-hs header and in MAC-hs PDU, whether there is padding data with instruction.This 1 bit flag is optional, because WTRU can determine the quantity of filling bit based on the size of FSN and previous segment.Do not need to indicate fragment size in the header, because the MAC-hs PDU only comprising last segmentation just comprises filling bit or because SID indicates the size of MAC-hs SDU.
Fig. 6 shows the MAC-hs SDU splitting scheme according to the second execution mode.Each MAC-hsPDU 604a-604n comprises the data from being no more than single MAC-hs SDU 602.All segmentation 608a-608m of MAC-hsSDU 602 subscribe size based on number of fragments (the total segmentation of S).A rule is defined to calculate described size.Preferably, start the size of S-1 segmentation be the size being greater than MAC-hs SDU and the multiple of S immediate with it divided by S.The size of last segmentation 608m is the size sum that the size of MAC-hs SDU 602 deducts a previous S-1 segmentation.Any one in MAC-hs PDU 604a-604n can comprise filling bit.Based on the fragment size of known MAC-hs SDU, WTRU knows which bit is filling bit.Each in PDU 604a-604n comprises one or more segmentations (not necessarily continuous) of MAC-hs SDU.Node B scheduler can neatly based on current channel condition and comprise in the past identical MAC-hs SDU segmentation MAC-hs PDU transmission success or unsuccessfully launch any subset of segmentation of MAC-hs SDU.
Than the first execution mode, the second selection of execution mode victory in segmented retransmission is more.Shortcoming is that the expense due to header and padding data and in each MSC-hs PDU is larger.
Fig. 6 also show the MAC-hs header format according to the second execution mode.MAC-hs header 606a-606n comprises VF, number of tiles (NFM) field of queue ID, TSN, MAC-hs SDU, FSDI and SID.Should recognize, the exact sequence of the information element in MAC-hs header is unimportant, can change.VF, queue ID, TSN are identical with the first execution mode with SID, therefore will no longer explain for the sake of simplicity.
The number of fragments of NFM field instruction MAC-hs SDU.If the number of fragments of MSC-hs SDU is fixed to particular value (such as, eight (8)), then can omit NFM field.The bit number of NFM field depends on possible number of fragments.Such as, if number of fragments may be 2 or 4, then NFM field can be one (1) bit.
FSID refers to the bitmap being shown in the segmentation of launching in MAC-hs PDU.The size of FSID is the number of fragments indicated by NFM field.Therefore, unless NFM field does not exist, otherwise NFM field will before FSID field.In office why not comprising in the MAC-hs PDU of the first segmentation can omit SID.
Fig. 7 shows the MAC-hs SDU splitting scheme according to the 3rd execution mode.Each in MAC-hs PDU704a-704n can comprise the signal subsection from maximum single MAC-hs SDU 702.Segmentation position in MAC-hs SDU 702 is arbitrary, and is instructed in the MAC-hsPDU header 706a-706n comprising this segmentation.Based on current channel condition and the transmission success in the past of MAC-hs PDU 704a-704n of segmentation or the failure that comprise identical MAC-hsSDU 702, Node B scheduler can be transmitted in any segmentation of any size of any position of MAC-hs SDU 702 neatly.
Fig. 7 also show the MAC-hs header format according to the 3rd execution mode.MAC-hs header 706a-706n comprises VF, queue ID, TSN, starting position identifier (SPID) and SID.Should recognize, the exact sequence of the information element in MAC-hs header is unimportant, can change.VF, queue ID, TSN are identical with the first execution mode with SID, therefore will no longer explain for the sake of simplicity.In office why not comprising in the MAC-hs PDU of the first segmentation can omit SID.
SPID indicates the starting position of the segmentation in MAC-hs SDU.Several scheme for definition position instruction granularity is possible.SPID can indicate the starting position of segmentation with bit or byte.Such as, if allow the size of MAC-hs SDU to reach 1024 bits, then the size of SPID represents it is 10 bits with bit, is then 7 bits with byte representation.
Alternatively, SPID can indicate a number-of-fragments, this number-of-fragments instruction starting position.Such as, if there is four (4) pre-established starting position for any MAC-hs SDU, then by extremely nearest for the size round-up of MAC-hs SDU multiple four, divided by 4, and adopt this numeral multiple to calculate starting position.Optionally, the quantity of pre-established starting position can be indicated by the separation field of the NFM being similar to the second execution mode.
In order to reduce expense, whether first bit can reserving SPID is the beginning of MAC-hs SDU to indicate starting position.If this starting position is the beginning of MAC-hs SDU, then SPID field can be a bit.Thus, if this segmentation originates in the beginning of MAC-hs SDU, then the size of SPID can be one (1) bit, otherwise is then N+1 bit, and wherein, N is the bit number of instruction needed for starting position.If the bit number needed for instruction starting position is greater than the quantity being launched segmentation, then this reduces expense.
Optionally, end position designator (EPID) or length indicator (LID) can be comprised in MAC-hs PDU header to indicate the length of segmentation end position in MAC-hs SDU or this segmentation respectively.Similar scheme may be used for encoding EPID and LID as SPID.
Fig. 8 shows the MAC-hs SDU splitting scheme according to the 4th execution mode.Each in MAC-hs PDU804a-804n comprises the combination of the combination from one or more segmentation 808a-808m of one or more MAC-hs SDU 802a, 802b or the one or more segmentation from a MAC-hs SDU and one or more complete MAC-hs SDU 802a, 802b.Any one in MAC-hs PDU804a-804n can comprise filling bit.Based on the fragment size of known MAC-hs SDU 802a, 802b, WTRU knows which bit is filling bit.The segmentation be associated with given MAC-hs SDU all has identical size, and this size is the quantity based on segmentation.Beginning S-1 segmentation size can be the size being greater than MAC-hs SDU and the multiple of S immediate with it divided by S.The size of last segmentation can be the size sum that the size of MAC-hs SDU deducts a previous S-1 segmentation.
4th execution mode allows Node B in identical MAC-hs PDU, launch last segmentation of MAC-hs SDU, and launches first segmentation (as shown in Figure 8) of follow-up MAC-hs SDU or complete one or more follow-up MAC-hs SDU (as shown in Figure 9).This allows more effectively to utilize radio resource because when in the MAC-hsPDU of last segmentation comprising MAC-hs SDU still location time, its allows Node B transmitting business data instead of filling bit.Still channel condition is after sending the first segmentation in improved situation to have caused segmentation at bad channel condition, and this may be particularly useful.
Fig. 8 also show the MAC-hs header format according to the 4th execution mode.MAC-hs header 806a-806n comprises VF, queue ID, SID, TSN, NFM, FSID, N field and F field.It should be pointed out that the exact sequence of the information element in MAC-hs header is unimportant, can change.VF, queue ID, TSN are identical with the first execution mode with SID, therefore will no longer explain for the sake of simplicity.
The group of SID, NFM, FSID, N and F is associated with one or more MAC-hs SDU.Multiple groups of SID, NFM, FSID, N and F can be comprised in MAC-hs PDU header.
NFM indicates the number of fragments with given group of SID, NFM, FSID, N and F MAC-hs SDU be associated.Such as, value ' 0' can indicate the group of SID, NFM, FSID, N and F not to be associated with any MAC-hs SDU segmentation.
FSID refers to the bitmap being shown in the segmentation of launching in MAC-hs PDU.(if in specific one group of SID, NFM, FSID, N, F) NFM is set to ' 0', then can remove FSID.
The instruction of N field has the quantity of the continuous whole MAC-hs SDU of the equal sizes be associated with SID, NFM, FSID, N and F.Value ' 0' may indicate current group of SID, NFM, FSID, N and F not to be associated with any complete MAC-hs SDU, and only be associated with segmentation.
F field is the mark that whether there is more multi-field in an instruction MAC-hs PDU header.Such as, if F field be set to ' 0', then have additional group of SID, NFM, FSID, N and F after F field, vice versa.
Optionally, can add DTSN field (not shown in Fig. 8) and launch to allow Node B the MAC-hs PDU comprising MAC-hs SDU, for this MAC-hs SDU, segmentation has been sent out and has successfully been received by WTRU.DTSN field identification WTRU needs the TSN deleted, and arrives comparatively upper strata (such as, MAC-d layer) in order to avoid copy MAC-hs PDU.Cause splitting still channel condition at bad channel condition and in improved situation, although WTRU successfully have received a part of MAC-hs SDU, wished that Node B sends complete MAC-hs SDU after sending first segmentation.
Following example illustrates and arrange according to the MAC-hs PDU header of the 4th execution mode.
Example 1: if Node B wants to launch latter two segmentation of MAC-hs SDU X and first segmentation of MAC-hs SDUY, then MSC-hs PDU comprises two groups of SID, NFM, FSID, N and F, and wherein first group is set to: SID>0, NFM>0, FSID ≠ 0, N=0, F=0, and second group is set to: SID>0, NFM>0, FSID ≠ 0, N=0, F=1.
Example 2: if Node B wants to launch latter two segmentation and next follow-up complete MAC-hs SDU Y and Z of MAC-hs SDU X, then being set to of one group of SID, NFM, FSID, N and F: SID>0, NFM>0, FSID ≠ 0, N=2, F=1.
Adopt segmentation, MAC-hs SDU can be split into two or more segmentations and described segmentation is separately launched.One or more segmentations of MAC-hs SDU may be lost.Figure 10 shows the segmentation of MAC-hs SDU 1002, and this MAC-hs SDU 1002 lost a segmentation.MAC-hs SDU 1002 is divided into four (4) segmentations.Each segmentation to be included in the MAC-hs PDU 1004a-1004d of separation and to be launched dividually.First, second and the 4th segmentation 1004a, 1004b, 1004d are successfully received by WTRU and are buffered.But the 3rd segmentation 1004c loses.Owing to lost the 3rd segmentation, segmentation 1004a-1004d cannot reassemble into MAC-hsSDU 1002.
WTRU spontaneously determines to transmit failure for particular fragments.As long as determine the H-ARQ process failure for a segmentation, WTRU just deletes identical MAC-hs SDU in the medium all segmentations to be reorganized of buffering.
Following mechanism can be used for determining fragment loss separately or with combination in any.WTRU can use the mechanism based on timer.WTRU arranges timer, and if timer expired before all segmentations that have received identical MAC-hs SDU, then and all segmentations that WTRU removing MAC-hs SDU etc. are to be reorganized.Timer can be reset when WTRU reception is the segmentation of a MAC-hs SDU part.Alternatively, only when first segmentation receiving MAC-hs SDU, timer is just reset once.The duration of timer can be configured by higher level (such as, radio resource controls (RRC) signaling).
Alternatively, when WTRU detects the failure of H-ARQ process, WTRU can remove MAC-hs SDU etc. all segmentations to be reorganized.When reaching the maximum times of H-ARQ re-transmission and WTRU can not successfully decode during MAC-hs PDU, this WTRU may detect the failure of H-ARQ process.Alternatively, when WTRU is just expecting to retransmit and receive the transmission of instruction new data (namely via the H-ARQ process data field on HS-SCCH) in identical H-ARQ process, this WTRU may detect the failure of H-ARQ process.
Alternatively, Node B can should delete all segmentations corresponding to MAC-hs SDU with new signaling mechanism to WTRU instruction.This signaling can by introducing new L1 or L2 signaling or realizing by changing traditional L1 or L2 signaling.
The segmentation of larger grouping has the advantage in mistake already explained hereinabove.But, if larger packet fragmentation is become less grouping, then create almost with the much smaller grouping that padding data fills up.The transmission that (being almost padding data) MAC-hs like this divides into groups will reduce the efficiency of transmission of MAC-hs and the air interface resource of waste preciousness.
Figure 11 shows the generation of the grouping of almost filling up with padding data.The size of MAC-hs PDU is 180 bits, and the size of MAC-hs SDU is 200 bits.MAC-hs SDU needs to be divided into two MAC-hs PDU.Beginning 180 bit completely with MAC-hs SDU fills up by the one MAC-hs PDU.But 20 bits only with MAC-hs SDU fill up by the 2nd MAC-hs PDU, and the remainder of the 2nd MAC-hs PDU (160bits) will be then padding data.More effective solution for this situation avoids segmentation, and alternatively launch larger transmission chunk sizes (the large original MAC-hs SDU size that must be enough to be used in 200 bits) and the H-ARQ process of dependence grouping Successful delivery.
Figure 12 shows the generation of two the MAC-hs PDU almost filled up with MAC-hs SDU bit.The size of MAC-hs PDU is 180 bits, and the size of MAC-hs SDU is 350 bits.MAC-hs SDU needs to be divided into two MAC-hs PDU.Beginning 180 bit completely with MAC-hs SDU fills up by the one MAC-hs PDU.2nd MAC-hs PDU almost fills up with residue 170 bit of MAC-hsSDU completely.In this case, the most effective solution allows segmentation MAC-hs SDU.Two MAC-hs PDU that continuous print TTI transmits will reduce the needs of excessive H-ARQ re-transmission, reduce the burden in MAC-hs downlink transmission system.
According to an execution mode, before segmentation MAC-hs SDU, the ratio between the MAC-hs PDU bit that Node B calculating MAC-hsSDU segmentation occupies and remaining MAC-hs PDU bit.Then, Node B compares this ratio and threshold value.Node B only has could split MAC-hs SDU when this ratio is greater than threshold value.
